The populations in all industrialized countries are aging rapidly and life life expectancies are increasing. Yet older workers are leaving the labor force at younger and younger ages. In some countries, the labor force participation rates of 60 to 64 year old men have fallen by 75% over the past...

The International Social Security (ISS) project compares the experiences of a dozen developed countries to study Social Security Programs and Retirement Around the World. The project was launched in the mid 1990s and was motivated by decades of decline in the labor force participation rate of...

This paper develops a theoretical foundation for the social cost of carbon (SCC). The model highlights the source of debate over whether countries should use the global or domestic SCC for regulatory impact analysis. I identify conditions under which a country's decision to internalize the...

Technology is the driver of labor allocation across sectors and occupations. Is the impact of technological change on developing countries similar to its impact on developed countries? Will developing countries follow the same development path that developed economies have taken? Our approach...

Are labor markets in higher-income countries more meritocratic, in the sense that worker-job matching is based on skills rather than idiosyncratic attributes unrelated to productivity? If so, why? And what are the aggregate consequences? Using internationally comparable data on worker skills and...

This paper develops the first globally comprehensive and empirically grounded estimates of mortality risk due to future temperature increases caused by climate change. Using 40 countries' subnational data, we estimate age-specific mortality-temperature relationships that enable both...

With few exceptions, economic analyses of "cap-and-trade" permit trading mechanisms for climate change mitigation have been based on first-best scenarios without pre-existing distortions or regulations. The reason is obvious: interactions between permit trading and other regulations will be...

Country incentives to participate in cooperative arrangements which either fully or partially internalize climate change externalities from carbon emissions involve critical asymmetries. Small countries trade off own country costs of carbon mitigation actions against their own benefits from...

We discuss most favoured nation (MFN) treatment in trade agreements, suggesting that its value to individual countries depends critically on the relevant model solution concept used to evaluate it. We analyze both rights to MFN treatment in foreign markets, and the obligation to grant MFN...

The last decade has witnessed an explosion in the number of regional trade agreements (RTAs). There seems to be a general if ill-defined belief on the part of many policy-makers, and among a number of academics as well, that there is more to a RTA than the traditional gains from trade. This...
